OBJECTIVE To explore the effect and mechanism of Prunus mume against hepatic fibrosis (HF). METHODS Male SD rats were randomly divided into normal control group (n=10) and modeling group (n=50). The modeling group established HF model using carbon tetrachloride. The modeled rats were randomly divided into model group (normal saline), positive control group [colchicine, 0.09 mg/(kg·d)], and P. mume low-dose, medium-dose and high-dose groups [1.35, 2.70, 5.40 g/(kg·d)], with 9 rats in each group. They were given the corresponding drug/normal saline intragastrically, once a day, for 8 consecutive weeks. After the last medication, the liver index was calculated, while liver function indexes, liver fiber indexes, oxidative stress indicators and inflammatory factors of rats were measured. HE staining was used to observe the pathological changes in liver tissue of rats; Masson staining was used to observe the degree of HF in liver tissue of rats; transmission electron microscopy was used to observe the ultrastructure of liver tissue in rats; TUNEL staining was used to detect liver cell apoptosis in each group of rats. Western blot method was used to detect the protein expressions of transforming growth factor-β1 (TGF-β1) and platelet-derived growth factor (PDGF) in liver tissue of rats. RESULTS Compared with normal control group, the levels of alanine transaminase, alkaline phosphatase, aspartate transaminase, total bilirubin, malondialdehyde, procollagen type Ⅲ protein, Ⅳ-type pre collagenase, laminin, hyaluronic acid, interleukin-6, tumor necrosis factor-α, as well as the protein expressions of TGF-β1 and PDGF in model group were increased significantly, while the levels of superoxide dismutase and glutathione peroxidase were significantly reduced (P<0.01); the HE, Masson staining and transmission electron microscopy observation results showed obvious HF characteristics in rats of model group. Compared with model group, varying degrees of improvement in above indexes were observed in P. mume groups, and the above 2021BSZR011) indicators of rats in P. mume medium-dose and high-dose groups were reversed significantly (P<0.05 or P<0.01). CONCLUSIONS P. mume has an anti-HF effect, which may be achieved through mechanisms such as antioxidation, anti-inflammation, reduction of collagen production, inhibition of PDGF protein expression, and regulation of TGF- β1 signaling pathway.

The paper introduces 5 books written by WANG Mengying, including Suixiju Chongding Huoluan Lun, Guiyan Lu, Wenre Jingwei, Wang Mengying Yi'an and Suixiju Yinshipu; and analyzes the ideas of diagnosis and treatment of cholera and the academic thoughts in treatment with acupuncture-moxibustion therapy. In pathogenesis, cholera is classified into cold and heat types. Cholera of heat type roots on qi and blood. If the pathogenic factors are mild and located shallowly, the sneezing method, followed by scraping method, is adopted to open meridians and collaterals, as well as the qi level, so as to eliminate pathogens. When the pathogens go deeply, the bloodletting technique is used to clean the toxic heat in blood level and reduce the reversed qi. For cholera of cold type, warm ironing moxibustion is delivered to promote qi circulation and disperse cold, and improve qi movement. If spasm and syncope occur in cholera, no matter of cold or heat identification, the emergent measure is operated with the external application of pungent, warm and salty herbal plaster at Yongquan (KI1). When the pathogens are almost eliminated, the herbal medicines are combined to treat the symptoms and remove the causative factors of the disease.

ObjectiveTaking the oligosaccharides in Rehmanniae Radix(RR) as the research object, the content determination method based on high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD) and thin layer chromatography(TLC) identification method were established to explore the content and distribution of oligosaccharides in different RR herbs and decoction pieces. MethodA total of 10 batches of fresh and raw RR, 12 batches of RR decoction pieces and Rehmanniae Radix Praeparata(RRP) were collected. A TLC identification method for fructose, sucrose, manninotriose, raffinose and stachyose in RR was established by using silica gel G thin-layer plates with ethyl acetate-water-anhydrous formic acid-glacial acetic acid(12∶6∶5∶4) as the developing agent and 10% sulfuric acid-ethanol solution as chromogenic agent. A HPLC-ELSD was used to determine the contents of fructose, glucose, sucrose, melibiose, raffinose, manninotriose and stachyose in different RR herbs and decoction pieces. Then principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) were used to analyze the contents of 7 kinds of saccharides in RR herbs and decoction pieces, and the differential components were screened with the value of variable importance in the projection(VIP)>1. ResultThe results of TLC identification showed that fresh RR, raw RR and its decoction pieces showed spots of the same color on the corresponding positions with the control products of stachyose, raffinose and sucrose, while the TLC of RRP showed spots of the same color at corresponding positions to manninotriose and fructose controls. The results of methodological investigations of 7 analytes met the requirements of determination. Only glucose, sucrose, raffinose and stachyose were detected in 10 batches of fresh RR and 10 batches of raw RR herbs, the average contents of which were 0.84%, 4.62%, 2.42% and 57.90% in fresh samples, while those were 3.16%, 9.36%, 7.05% and 38.10% in raw samples, respectively. In 12 batches of RR decoction pieces, the contents of the above seven sugars(fructose, glucose, sucrose, melibiose, raffinose, manninotriose and stachyose) were 1.68%, 4.27%, 9.96%, 0.53%, 6.85%, 3.05% and 37.52%, respectively. In 12 batches of RRP, the contents of the above seven sugars were 10.62%, 11.01%, 1.25%, 3.35%, 1.12%, 28.16% and 6.39%, respectively. The results of multivariate statistical analysis showed that fresh RR, raw RR and RRP could be distinguished from each other by the contents of the 7 sugars, and the main differential components were stachyose, sucrose, raffinose and manninotriose. ConclusionIn terms of oligosaccharides, the contents and types of saccharides in different herbs and decoction pieces of RR are quite different, and the TLC identification method based on this can be used to distinguish raw RR from RRP, which can lay a foundation for improving the quality standard of RR and developing and applying oligosaccharides in different processed products of RR.

Sha (痧) is an acute infectious disease characterised by the appearance of rashes on the skin, caused by exposure to epidemic toxin and pestilent qi. Sha Zhang Yu Heng (《痧胀玉衡》) discussed the treatment principles and methods, and listed collateral bloodletting as one of the main treatments. Through organizing the articles and proved cases, we found that the author believes Sha (痧) is caused by epidemic pathogen, belonging to heat toxin with rapid changes, so timely treatment for qi and blood simultaneously could achieve the effect of transforming qi into defensive qi. Sha Zhang Yu Heng focuses on patient's position during treatmet, the material of the needle, the site of treatment, the quantum of stimulation and the operation of the contraindications and other essentials. According to the depth of the disease location, use traditional Chinese herbal medicine, scraping together to identify the root of the disease. In addition, diet suggestions for the prevention of the recrudescence of disease are also described in detail.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.
